The picture illustrates the solar panels that power all of the appliances in Joshua's house. What energy transformations occur that enable Joshua to bake cookies for his family in the oven? (1 point)
Responses
light energy → electrical energy → heat energy
light energy → electrical energy → heat energy
heat energy → chemical energy → light energy
heat energy → chemical energy → light energy
heat energy → light energy → heat energy
heat energy → light energy → heat energy
light energy → electrical energy → chemical energy
The correct answer is: light energy → electrical energy → heat energy
The correct transformation of energy that enables Joshua to bake cookies for his family in the oven is:
light energy → electrical energy → heat energy.
To determine the correct energy transformations that occur in this scenario, we can break it down step by step:
1. Solar panels convert light energy from the sun into electrical energy. This is because solar panels contain photovoltaic cells that absorb sunlight and use it to generate an electric current. So, the first transformation is from light energy to electrical energy.
2. The electrical energy generated by the solar panels is then used to power the oven. The oven converts this electrical energy into heat energy through a process called Joule heating. This is accomplished by passing an electric current through heating elements within the oven, which then produce heat. Therefore, the second transformation is from electrical energy to heat energy.
So, the correct energy transformations that enable Joshua to bake cookies for his family in the oven are:
light energy → electrical energy → heat energy.
